"These days, the 'revolution' is all about Linux. The word alone has become a catchcry for everything anti-establishment, anti-Bill, and anti-licensing fees. If you listen to the hype, it's being used everywhere, in businesses of all sizes, to do everything but make the coffee. Just because everybody's using Linux, however, doesn't mean everybody's happy for that fact to be known, as I found recently while looking for potential candidates for this special report about companies that had made the switch from Windows and Linux, and vice versa."
